Graham Greene wrote the brilliant screenplay for The Third Man and it was directed by Carol Reed. The movie really stars Joseph Cotton with a smaller but charismatic role for Orson Welles. That line is the most remembered of the movie (as is the score) and is spoken by the wily Harry Lime.
Very good movie.
Not terribly good history.
The other thing the Swiss give us is an entirely laudable refusal to bow the knee to arrogant nobility, at a time when aristocrats ruled almost universally. A precursor to America in many ways.
